Section A

Learning objectives

After studying this chapter you should be able to:

• give a brief overview of different views of the role of government in the economy

• list key issues confronting southern African governments regarding their role in the economy

• distinguish between the main institutional categories of the public sector

• discuss the salient features of and trends in the size and composition of the South African public sector

• discuss various aspects of the relationship between the public sector and the rest of the economy.

Chapter outline

The aim of this chapter is to demarcate the study field of public economics with reference to key issues and fiscal challenges facing the South African economy and the southern African region in general. The role of government is fairly similar across the region, and in the sections and chapters that follow we describe the nature of the South African public sector against the backdrop of the theory of public economics and contemporary views on the role of government in the economy. We also consider the interaction between the public, household, and private (business) sectors of the economy.

Answers to self-assessment exercises

1.1 Distinguish between the following:

• positive and normative economics

• general government and public sector

• resource use and resource mobilisation.

Answer (brief guidelines):

• Positive economics studies the nature and the consequences of decisions taken.

• Positive economics attempts to predict what could be expected to happen if certain steps, specified at the time are taken.

• Normative economics focuses on studies the question: ‘What ought to be the situation?’

• Once a situation is described, normative economics seeks criteria to determine whether that situation is acceptable or whether it ought to be adjusted to become closer to what the criteria require.

• General government embraces the three spheres of government in South Africa: central, provincial and local government, and therefore forms the wing of the public sector that renders services funded out of taxation.

• The public sector is the wider concept which adds the public enterprises or public corporations to general government.

• Public enterprises are those institutions which deliver public services but on a commercially-based system charging user charges.

• From a management point of view, public corporations are run by Boards of Directors that are appointed by the government.

• Resource use is one way of measuring the magnitude of government expenditure and captures the exhaustive expenditures of government and the non-exhaustive expenditure.

• Exhaustive expenditure refers to the expenditure on final goods and services while non-exhaustive expenditure refers to the transfer payments to beneficiaries outside the public sector.

• In addition to exhaustive and non-exhaustive expenditure government also makes transfer payments to households, business enterprises and the foreign sector.

• When these transfer payments are added to the exhaustive and non-exhaustive expenditure, the so-called resource use by government, we get the total amount of resources mobilised by the government.

1.2 Explain the difference between the individualistic and public interest view of government.

Answer (brief guidelines)

• Individualistic or mechanistic view recognises the supremacy of individual welfare and choice.

• Government institutions and their actions must reflect these preferences.

• Government must therefore correct for market failures which stand in the way of individual welfare.

• Consequently this approach focuses sharply on efficiency and the achievement of economic growth.

• The public interest view sees the goals of society as separate from the goals of individuals.

• Society welfare or the national interest must thus be advanced.

• Consequently the public interest view puts strong emphasis on distributional issues affecting matters such as poverty.

3. What are the features of the developmental state?

Answer (brief guidelines):

• Explicit development objectives are formulated by the state.

• The state assumes powers and establishes institutions that can strive for achieving these objectives.

• Sufficient power, autonomy to act and the capacity to act are concentrated in the state to achieve development objectives.

• The developmental state is further characterised by:

o An elite determined to see development taking place

o A powerful bureaucracy capable of driving the development process

o Management of economic interests outside the public or state sector

o State intervention that distort relative prices when this is deemed necessary for the sake of development.

4. Briefly review the salient changes in the size and composition of the South African public sector during the past few decades. Which of the changes, in your opinion, are incompatible with the requirements of a thriving economy?

Answer (brief guidelines):

• Consider Table 1.1.

[pic]

• Choose at least the two decades before 1990 and make a comparison with the period after 1990 to date.

• Compare taxes as percentage of the GDP for the selected periods.

• Compare the trend in general government consumption with the trend in government investment.

• Consider the trend in subsidies and current transfers and determine what causes the rising trend.

• Compare the trend in resource use with the trend in resource mobilisation.

1.5 Give an overview of the various dimensions of the relationship between the public sector and the rest of the economy.

Answer (brief guidelines):

• Draw a circular flow diagram and then identify and describe

o Government as a supplier of public goods and services.

o The influences of government purchases of goods and services.

o The economic consequences of funding state expenditures.

o How a budget imbalance influences the balance between savings and investment.

o How the funding of a budget deficit affects macroeconomic stability.

o How the condition of the economy affects the government’s activities in the economy.
